Alyson Hannigan stopped by
"Watch What Happens Live" on Bravo Wednesday night (May 8), where she participated in
Andy Cohen's "Plead the Fifth" segment -- though Hannigan did not plead the Fifth to any questions.

Cohen: "Who was the most annoyed to be on
'Buffy the Vampire Slayer' by the end of the show's run?"
Alyson: "Sarah [Michelle Gellar]. [
audience oooohs] She had a big career going. It was a lot of work."

Cohen: "What is the most annoying thing about 'Buffy' fans?"
Alyson: "The only ones that annoy me are the ones that show up at my house. Just ... don't come to my house."

Cohen: "Tell us one 'Buffy' on-set hook-up we did not yet know about?"
Alyson: "I think Nick [Brendan] and I might have kissed once ... he might have had a boob or something."

Saucy.

Update:
A previous version of this article said that Cohen asked "Who was the most annoying," though upon repeated viewings, we think he actually says, "Who was the most annoyed." We apologize for the confusion.Update II: Hannigan
says on Twitter it wasn't a diss towards SMG: "It wasn't a diss! She said that herself! She did an interview saying that is why the show was ending! No diss, just fact."
